Struct LineWriter
pub struct LineWriter<W: AsyncWrite> { /* private fields */ }Wrap a writer, like BufWriter does, but prioritizes buffering lines
This was written based on std::io::LineWriter which goes into further details
explaining the code.
Buffering is actually done using BufWriter. This class will leverage BufWriter
to write on-each-line.
Implementations
impl<W: AsyncWrite> LineWriter<W>
fn new(inner: W) -> SelfCreate a new
LineWriterwith default buffer capacity. The default is currently 1KB which was taken fromstd::io::LineWriterfn with_capacity(capacity: usize, inner: W) -> SelfCreates a new
LineWriterwith the specified buffer capacity.fn buffer(&self) -> &[u8]Returns a reference to
buf_writer's internally buffered data.fn get_ref(&self) -> &WAcquires a reference to the underlying sink or stream that this combinator is pulling from.
